I can't remember if I followed up or not, but over on the ietf-822 list there
were 3 or 4 products mentioned that had code but shipped with the ability 
configured
disabled.  Gnus seems to be the largest user base that would potentially handle
a message/partial either incoming or outbound.  This implies "It's only of use 
if
you already know a priori that your recipient is running an uncommon mail 
stack".

(Further research shows that I was probably incorrect in saying that exmh can't
handle reassembling a message/partial - further looking at the code indicates
that if 'mhstore' is able to deal with the message fragments not being in
order, it should work, but I haven't tested it.  There's zero support for
passing -split to 'send'.
